Built as the world's first deep-ocean submersible, Alvin has made more than 4,200 dives and can reach 63 percent of the global ocean floor (reaching depths of 14,764 feet/4,500 meters). (Mark Spear, Woods Hole Oceanographic Institution)

From the Seafloor to the Space Station

Listen to the first call between ocean explorers and astronauts

UPDATE (EVENING OF JAN. 26) -- The recorded conversation between Tim Shank and Suni Williams is now available on the web. Click here
for more information. Please check this page during the week of
January 29 for updates on the conversation -- we hope to have
transcripts, answers to questions, and re-broadcast times.

He is two miles under water; she is 200
miles up in the atmosphere. They both work in small, confined spaces,
looking out onto vast, unpopulated expanses. He is
out of the reach of sunlight, buried under a blanket of perpetual darkness;
she sees the Sun rise 15 times a day...if she has any time to look for
it. Both are explorers of the last frontiers.

WHOI marine biologist Tim Shank, diving in the Alvin submersible, will compare notes on life, science, and exploration with NASA astronaut Sunita “Suni” Williams
as she orbits on the International Space Station. And you can be a part
of that conversation: Students, educators, and science lovers submitted
questions for Tim and Suni to answer on the air and the web. Visit the Questions and Answers page to read replies, which should be available by January 29.

To learn more about the oceanographic expedition to East Pacific Rise, 500 miles off the coast of Mexico, visit the Student Explorer at Sea (SEAS)
program, which provides updates from the research team, lessons for
students and teachers, and gee-whiz facts about life and work at sea.
The expedition is funded by the National Science Foundation as part of
its Ridge2000 research
initiative. You can also learn more about deep-sea research at Venture Deep Ocean.

To
follow the activities of astronaut Sunita Williams and her colleagues
as they continue the construction of the space station and carry out
science experiments on plants, materials, and themselves, read her
online journal, which is updated several times per month.
